4) make syslog() use strerror_r() Actually, for known errno values, strerror() is thread-safe on FreeBSD. It just returns a pointer into sys_errlist[]. For invalid values it stuffs "Unknown error: ##" into a static buffer and returns a pointer to that. I'll update the PR to make syslog call strerror_r(). http://www.freebsd.org/cgi/query-pr.cgi?pr=standards/72394 -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
